Title: Circular Express reference in createServer()

If an Express server is created and returned from another project we loose the reference to Express itself. This way we can carry it around.

Example
```javascript
var myProject = require('myProject')
, app = myProject.server(); // returned Express app

app.configure(function(){
app.use(app.express.bodyParser());
/* ... */
});

app.listen(3000);
```
We can do `app.express`
